HOW_MANY_RESEARCH_STEPS = 3
QUESTION_MULTIPLIER = 3 # WE START WITH 1 QUESTION AND THEN MULTIPLY IT BY THIS NUMBER FOR EACH RESEARCH STEP

take these steps one by one:

1- check if you have researcher(queries: list) function in tools.py file(if not create the function in the file)
2- if not create it using this perpelxity api call:
---------
from openai import AsyncOpenAI
import os
import asyncio
from termcolor import colored

YOUR_API_KEY = os.getenv("PERPLEXITY_API_KEY")

async def researcher(queries: list) -> list:
    try:
        print(colored("Starting parallel research queries...", "cyan"))
        
        async def process_query(query: str) -> str:
            messages = [
                {
                    "role": "system",
                    "content": (
                        "You are a versatile research assistant with expertise in both academic and general web research. "
                        "Your task is to provide comprehensive, accurate, and well-structured responses that: "
                        "1) Draw from both academic sources and reliable web resources "
                        "2) Break down topics into clear, accessible explanations "
                        "3) Include relevant data, statistics, and expert insights from various sources "
                        "4) Consider multiple perspectives and fact-check information "
                        "5) Distinguish between academic research and general web content "
                        "6) Provide a mix of scholarly citations and credible web references "
                        "7) Evaluate the reliability of web sources and identify potential biases "
                        "8) Incorporate recent developments and real-world applications "
                        "Please balance academic rigor with practical, real-world relevance. "
                        "When using web sources, prioritize authoritative websites, industry experts, and verified information. "
                        "If uncertain about any information, clearly indicate this and provide both academic and web-based resources for further research."
                    ),
                },
                {   
                    "role": "user",
                    "content": query,
                },
            ]

            try:
                client = AsyncOpenAI(api_key=YOUR_API_KEY, base_url="https://api.perplexity.ai")
                print(colored(f"Processing query: {query[:50]}...", "yellow"))
                
                response = await client.chat.completions.create(
                    model="llama-3.1-sonar-large-128k-online",
                    messages=messages,
                )
                return response.choices[0].message.content
            except Exception as e:
                print(colored(f"Error processing query: {str(e)}", "red"))
                return f"Error processing query: {str(e)}"

        # Create tasks for all queries
        tasks = [process_query(query) for query in queries]
        
        # Execute all tasks concurrently
        results = await asyncio.gather(*tasks)

        print(results)
        
        print(colored("All research queries completed successfully!", "green"))
        return results
        
    except Exception as e:
        print(colored(f"Error in researcher function: {str(e)}", "red"))
        return [str(e)] * len(queries)
    
you will run this function for each research step as a terminal command only with "python -c from tools import researcher; researcher(queries)"
    
3- next folow HOW_MANY_RESEARCH_STEPS steps AS FOLLOWS:
    1- ask a basic but comprehensive question about the topic or question user is interested in
    2- run the researcher function with that question
    3- create a research.md file with general skeleton structure with general information about that topic based on the researches output
    4- multiply the question by QUESTION_MULTIPLIER and run the researcher function again with the new more in depth questions
    5- update the research.md file with the new information including charts, graphs, tables, etc. make sure it is as beautiful as it is accurate and informative. we belive in you!!

LangChain Python Inference Backend AI Rules
You are an expert in Python, LangChain, and scalable AI application development.

Key Principles
Provide a concise, technical response with accurate Python example code using LangChain v0.2.
Prioritize functional and declarative programming, and avoid classes whenever possible.
Use LangChain Expression Language (LCEL) for chain implementation.
Use descriptive variable names, for example: is_retrieval_enabled, has_context.
Directory and file names use lowercase letters and underscores, for example: chains/rag_chain.py.
Linkers, retrievers, and utility functions should prefer named exports.
If you are unsure about the LangChain module, you can refer to the concept guide .



LangChain/Python
Use 'def' for pure functions and 'async def' for asynchronous operations.
All function signatures are type-hinted. For input validation, Pydantic v1 models are used.
Avoid unnecessary parentheses in conditional statements.
For single-line statements in conditionals, use concise syntax (e.g., 'if condition: return result').
By default 'python-dotenv' is used to load environment variables.
Make sure to use the structure of the LangChain 0.2 library:
Import common data structures from 'langchain_core' instead of from 'langchain'.
Example: from langchain_core.prompts import PromptTemplate
Error handling and validation
Prioritize error handling and edge cases:

Handle errors and edge cases at the beginning of the function.
Use early returns for error conditions to avoid deeply nested if statements.
Put the happy path at the end of the function to improve readability.
Avoid unnecessary else statements; use the if-return pattern instead.
Use guard clauses to handle preconditions and invalid conditions early.
Implement proper error logging and user-friendly error messages.
Use custom error types or error factories for consistent error handling.
Dependencies
Core dependencies:

langchain
langchain-community
langchain-core
langgraph
python-dotenv
Optional dependencies (included only if used):

langserve (for building RESTful services)
faiss-cpu (for vector storage in RAG)
tavily-python (for Tavily search integration)
unstructured (for document parsing)
Environment variables
Use python-dotenvto load environment variables.
.env.exampleInclude all required environment variables in :
OPENAI_API_KEYand OPENAI_API_BASEfor OpenAI compatible models
LANGCHAIN_TRACINGV2="true"Used to enable LangSmith tracing
LANGCHAIN_PROJECT="YOUR_PROJECTNAME"For LangSmith project names
LANGCHAIN_API_KEY="YOUR_API_KEY"For LangSmith API access
TAVILY_API_KEY="YOUR_API_KEY"(Only when searching with Tavily)
Add any other necessary API keys or configuration variables
LangChain Specific Guidelines
Use LCEL to implement the chain, refer to the LCEL cheat sheet .
Use Pydantic v1 models for input validation and responsive patterns.
Use declarative chain definitions with clear return type annotations.
Prefer transparent LCEL chains over pre-built black-box components.
Use asynchronous functions and caching strategies to optimize performance.
Use LangGraph to build stateful multi-actor applications with LLM.
Implement proper error handling for LLM API calls and chain executions.
Model Usage
First consider using 'langchain-openai' for OpenAI and OpenAI compatible models.
Make 'gpt-4o-mini' the default OpenAI chat model.
If you are not using OpenAI or compatible models, consider using standalone vendor packages for model integration.
Always check for the existence of required environment variables before initializing a model.
For tool calls and structured output, refer to the supported models and use the appropriate method.
Performance Optimization
Minimize blocking I/O operations; use asynchronous operations for all LM API calls and external requests.
Implement caching for frequently accessed data and LLM responses.
Optimize tip template and chain structure to improve token usage efficiency.
Use streaming responses for long-running LLM tasks.
Implement streaming in the main function for better testing and real-time output.
Chain Implementation
Always try chain implementation using LCEL first.
If you are considering a legacy chain, use its LCEL equivalent according to the migration guide.
LLMChain migration
ConversationalChain migration
RetrievalQA migration
ConversationalRetrievalChain migration
StuffDocumentsChain migration
MapReduceDocumentsChain migration
MapRerankDocumentsChain migration
RefineDocumentsChain migration
LLMRouterChain migration
MultiPromptChain migration
LLMMathChain migration
ConstitutionalChain migration
For document loading and parsing in chains and proxies, use unstructuredthe library (included in dependencies) if needed.
Do not place a main function in a chain or proxy file. Use main.pyas the entry point of your application.
RAG (Enhanced Generative Search)
Follow the RAG tutorial for implementation guidelines for vector storage:
Use FAISS whenever possible (include faiss-cpu in your dependencies).
If FAISS is not applicable, consider other vector storage .
For the retriever, note that it returns a list of documents that may require further processing, format_docs()e.g.
Before considering pre-built black-box retrievers, first implement a transparent LCEL chain.
Agent Implementation
Use LangGraph to build stateful multi-actor applications with LLM.

For simple ReAct agents, use the pre-built ReAct agents .
For complex proxies, implement LangGraph workflows. When using tools in LangChain or LangGraph:
When tools are needed, tool nodes are prioritized .
Where applicable, use Tavily as the primary search tool (include tavily-python in the dependencies).
Implement structured output for compatible models . For complex control flows, consider the following approaches:
Create a subgraph .
Creating Branches for Parallel Execution Create branches for parallel execution .
Create map-reduce branches for parallel execution Create map-reduce branches for parallel execution .
Correctly control recursion limits in graphs .
Create a langgraph.jsonmanifest file to configure the proxy for compatibility with LangGraph Studio. Do not place a main function in the proxy file. Use main.pyas the entry point for your application.
Chatbot Implementation
Refer to the chatbot tutorial to implement the function.
Use an in-memory component to maintain the session context.
Implement proper input validation and output formatting for the chat interface.
LangServe Integration
Use LangServe to create a RESTful interface for the inference logic.
Follow LangServe's best practices to build and deploy LangChain applications.
Implement proper error handling and input validation in the LangServe endpoint.
Create test cases using LangServe Soak to ensure endpoints are functional.
Consider using LangServe's built-in playground for interactive testing and demonstrations.
If necessary, add custom middleware for logging, CORS, or authentication.
